Compare multiple data series over time in a vertical bar or column chart. FlexChart supports displaying negative values below the axis origin.
Bar Stacked Charts
Stacked charts demonstrate the part-to-whole relationship for displaying the cumulative values of categories. FlexChart provides options to stack column charts in groups.
Bar Stacked 100 Charts
Compare percentages for each value within the total. The cumulative proportion of each stacked column always totals one hundred percent.
Rotate the column chart to compare multiple, categorical data series in a basic horizontal bar chart.
Floating Bar Chart
A floating bar or range column chart shows two values, a minimum and maximum, for each column or bar. The plot can be rotated to create a Gantt-style chart as well.
Tornado charts, also known as wing bar or butterfly charts, are a variation of bar charts for comparing two sets of data values in a vertical stack of horizontal bars.
Display changes in data over short and long periods of time with a basic line chart with optional symbols.
Line Stacked Charts
Stacked line chart series do not overlap because they are cumulative at each point, and ideal for visualizing the overall total.
Step line charts help visualize changes at a specific point. Data points are connected through vertical and horizontal lines. Display symbols or fill the area.
Spline charts connect the data points with smooth lines and use numeric, category, datetime, or logarithmic axis to plot data. WinForms spline charts support symbols, stacking and axis rotation.
Fill in the area below the line to demonstrate trends in similar categories. WinForms area charts support stacking, spline and axis rotation.
Range Area Charts
Fill in the area below the line to demonstrate trends in similar categories. Shows variations in the data values for a given time.
Demonstrate correlation between data points and a set of numerical data along the x-axis and the y-axis. Scatter charts combine values into single data points and display uneven intervals or clusters.
Create rich, visually appealing data modeling and financial charts with bubble charts. This WinForms chart control allows you to display your data series as a set of differently-sized symbols in the chart space.
The candlestick chart displays the Open, Close, High, and Low Stock Prices for each day in the series. The vertical bar spans the High and Low values for the day.
Also known as high-low-open-close, HLOC charts illustrate movements in the price of a financial instrument over time.
More Financial Charts
With Studio Enterprise you get FinancialChart, which includes 9 additional chart types including Heikin-Ashi, Kagi, Renko and more.
WinForms pie charts show how parts of a whole add up to 100%. FlexPie features include doughnut, exploded slices, animation, selection, and rotation.
Visualize hierarchical data from a root node (center) outward to lower hierarchies. A segment of the inner circle is a parent to the segments of the outer circle which lie within the angular sweep of a parent.
Multiple Pie Charts
Use FlexPie to visualize more data in a single chart by creating multiple pie chart "series" using the same data source. An effective way of presenting data, especially if the intent is to show one section relative to the whole.
Display multivariate observations with an arbitrary number of variables. FlexRadar supports line, area, column, scatter and stacked chart types.
Radar Area Charts
Create a windrose chart using FlexRadar and the Column chart type. This visualization lets you display changes in the radar through radiating columns with stacking support.
Create circular graphs to display multivariate observations with an arbitrary number of variables. FlexRadar can generate polar charts with lines, columns, filled areas and custom symbols.
Error Bar Charts
Error bars help you see margins of error and standard deviations at a glance. They can be shown as a standard error amount, a percentage, or a standard deviation.
Graphically depict groups of numerical data through their quartile, mean, median and outliers.
Diagram consists of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval. Supports ranged axes, Gaussian/bell curve, running totals and Pareto charts.
A waterfall chart helps understand the cumulative effect of sequentially introduced positive or negative values. Optionally, display auto-calculated intermediate totals in the waterfall chart.
A break-even chart shows the sales volume level at which total costs equal sales. The chart plots revenue, fixed costs, and variable costs on the vertical axis, and volume on the horizontal axis.
Manage a project with a Gantt chart and never miss a step. Includes dependencies and percent complete, start and end dates for each task, and information such as completion states and task dependencies.
Visualize stages of a process, such as a sales funnel, using a funnel shape. Supports a triangular or rectangular shape.
Display hierarchical information combined with relative quantity. Highlight hierarchical, tree-structured data as a set of nested rectangles and help to analyze the anomalies in the data set.
This specialized chart represents data values using colors and is especially useful in plotting large, complex data. Customize the discrete gradient color scale and gradient color axis.
FlexChart supports Direct2D rendering on the desktop for the fastest performance. DirectX is the most direct and optimal approach to drawing graphics when performance is a concern. FlexChart can render 50k data points in about 5 milliseconds on an average laptop. Or, you may use the standard GDI+ rendering with no dependencies on DirectX libraries.
Zooming and Panning
Zooming in charts allows users to select the area they want to enlarge by clicking and dragging the mouse, enabling them to analyze the data-packed charts at a granular level.
Add interactive line markers or cross-hairs to show information about a specific point on your chart. Optionally, draw markers along the axis too.
Drill-down and Selection
Select a single data point or an entire data series in your chart. With drill-down, you can click a data point to drill down into the details, or click on the breadcrumb to return to a higher level.
Choose one of FlexChart's 20 built-in color palettes including sequential and diverging palettes which are helpful in visualizing ordered or diverging data sets. Or customize your own palette with full opacity and gradient support.
Add animation when the WinForms chart control is loaded or when data points are updated. Choose an easing function and how to animate the data points.
Custom Data Points
Configure the chart axes and gridlines to your desired specifications. FlexChart supports multiple axes, major and minor gridlines, tick marks, axis origin, reversed axes, rotated axis labels, logarithmic scaling and more.
Scaling and Scrolling
FlexChart allows you to add axis scrollbars to the X and Y axes, allowing the user to simultaneously scroll and scale the axis to better visualize the data.
Axis Labels and Grouping
Improve chart readability by displaying hierarchical groups in axis labels. Avoid overlapping by wrapping labels to a second row or rotating the angle.
Axis Origin and Position
FlexChart axes are flexible and support many features. Create a quadrant chart by moving the axis origin. Compare multiple series using multiple Y axes. Reverse any axis to change the visualization.
Legends represent the mapping between colors, symbols, and data series on a chart. Grouping the legend items helps organize the data.
Allow users to toggle the visibility of the series through the legend. This feature is toggled on or off by setting one property on FlexChart.
Further customize the legend with scrolling or custom icons. You can also easily enable legend toggle to hide series.
Runtime Chart Designers
FlexChart for WinForms is designed with the end-user in mind. Put the power of customization in your user's hands with runtime chart designers. Plus, save and reload user-defined charts with JSON serialization.
Your users can annotate the WinForms charts at runtime using text, images and shapes. Editing annotations allows the application user to define events and points of interest and relies less on the developer.
Chart Toolbar & Ribbon
The runtime chart toolbar and ribbon helps the end-user customize the chart appearance. Users can change the chart type, color palette, legend position, data labels, add series, set ranges, export and print.
Data Labels and Tooltips
Display precise chart values in labels attached to each data point. FlexChart can automatically display the formatted value or percentage within labels and tooltips. Prevent data labels from overlapping so all data is visible.
Easily combine any Cartesian chart types into a single plot using FlexChart's flexible model. Each series can be set to a different chart type, allowing endless composite chart combinations.
Multiple Plot Areas
Define multiple plot areas to display plots stacked horizontally and vertically. Stacking plot areas helps visualize multiple series in a single chart.
With the range selector, you can enable scrolling between two charts where one is a preview of all data and one is filtered (or zoomed) to the selected range for closer analysis.
Add trend lines to show trends in data and make predictions. FlexChart supports several built-in regression and non-regression trendlines such as linear, average and polynomial.
Chart Export and Printing
Print multiple charts to a page with scaling and axis display options. FlexChart for WinForms can also be exported to an image or XML/JSON for serialization.
