How to change X and Y axes sources in the waveform chart

[mike1928]

Hello

I have some data that they are read from PLC by Modbus TCP protocol. Such as sensor voltage, loadcell number, and encoder number, and they are shown in the VI by numeric indicators.

Now, I want to draw a real-time line-graph by these data and also want to define X or Y axis by them. I mean, I want to change X or Y axis source to other or external sources. For example, the X-axis be defined as the sensor voltage, and the Y-axis be defined as the loadcell number, and the proportional line-graph be drawn. 

Could someone please guide me on how to that step by step?

Best regards

You talk about a waveform chart, but then talk about defining a sensor voltage for the X axis.

You need to use an XY graph.  Then to change what an X axis is and a Y axis is, you just need to bundle up the correct wires with that data.  Look at the help and the XY Graph example to see the different ways of combining data.
