Overview
This example shows how to manually add multiple Y-axes to a WaveformGraph .NET component and how to programmatically assign a plot in a WaveformGraph to one of the added axes.
Description
This example is a modified version of an example shipped with Measurement Studio that is available at the following location: Start » All Programs » National Instruments » Measurement Studio 2010 » .NET Examples. Once in the Measurement Studio Examples directory navigate to the following location: <Measurement Studio Examples>\UI\WindowsForms\Graph\Plotting
Requirements
Steps to Implement or Execute Code
- Open the MainForm of the attached completed example or the example mentioned above.
- Right click on the WaveformGraph component and select "Edit Yaxes..."
- In the YAxis Collection Editor window press the Add button to create an additional Y-Axis and then press OK.
- Add the following code to the end of the OnTimerTick function so the axes are dynamically assigned to the plots when the number of plots change
/**
* The following code determines how many plots should be assigned to the axes available. If there are more plots than axes the remainder
* of the plots are left on the default axis.
* After finding the number of Axes available, the plots associated with the WaveformGraph are iterated through and the plots Y-Axis is modified
* to use one of the other Axes available.
**/
int plotIndexIter;
for (plotIndexIter = 0; plotIndexIter < Math.Min(sampleWaveformGraph.Plots.Count, sampleWaveformGraph.YAxes.Count); plotIndexIter++)
sampleWaveformGraph.Plots[plotIndexIter].YAxis = sampleWaveformGraph.YAxes[plotIndexIter];
- Run the application to see multiple plots each with their own Y-axis on one WaveformGraph
