how to achieve this in waveform-chart?

[MSD100]

I do use waveform chart in which 3 waveforms are stacked. My x-axis represent current time and y axis is a some quantity...Please look at the picture attached....is it possible to do this in waveform chart? Whenever mouse/cursor is on waveform it should display y-axis value corresponding to that point.......

Hi msd,

use cursors and enable the cursor display...

And inline a smaller picture next time!

Hi msd,

so you may use a graph instead...

Hey GerdW,

So far I know to display a subset of a larger set of data using cursor.. but no idea how to display the moving cursor Y value as per your suggestion.. I m using property node to get active plot information of X and Y scale and then .. formula i m using ..

Conv_X = (XScl_Max - XScl_Min)/PlotArea_Width;
Conv_Y = (YScl_Max - YScl_Min)/PlotArea_Height;

Graph_X = XScl_Min + Conv_X * (Mouse_X - (YScl_Left + YScl_Width));
Graph_Y = YScl_Max - Conv_Y * (Mouse_Y - (XScl_Top - PlotArea_Height));

inside formula node .... using above values I get the moving cursor value of Y scale.. as asked by thread author in starting ..

If there is some short way then i will like to learn it ..

Regards

Hi HS,

do you use 2 different logins?

If you would enable/show the cursor palette of the graph you would actually see those values instantly...

When you want to calc with them you can use the properties of the cursor to get the x- and y-value! No calculation of graph size and so on needed...
