Stripchart issue with CVI8.5

[SiggiReich]

Hi,

in my application I have the same problem. Since years we use stripcharts to inform our customer about his vehicle driving style.

We use several physical values to display in one chart. Due to the fact that CVI can only manage one left and one right Y-axle we added eight more axles on each diagram. To create the axles itself we use the canvas function and draw the necessary lines our self.

I’m a little bit disappointed about the NI reaction!

I only hear that there is no idea when the problem is solved and whether a patch comes ore not nobody knows.

I think that it can be developed by NI a chart that allows multiple Y-axes too. I am in the same problem. I use the canvas function, but I think that is not the better way to do it, but using CVI, it is the only way.

I had some problems also plotting real time data from a data source that doesn't have a fixed frequency. I have to control all history data, time slice etc by myself and it is a hard work. I think it is not too much ask for a strip chart that allows me to pass a parameter the value and the time that the data was acquired.

Luis has posted a patch for the overlapped control bug here.

For what I've tested so far it seems to work..

Canvas is not the only way. See attached screenshot for an old application using multiple traces on a 7.0.0 stripchart. Rather than use invisible buttons, we detected the trace that an operator was interested in by measuring the mouse position over the control.
