[Ex-jobb]

Hello!

We are using a waveform chart and we like to be able to change the look of the chart with a menu-ring. You should be able to choose between “stack plots” and “overlaid plot”.
Does anyone know how to do this?
We have a solution with two charts but they start to draw the signal where it stopped last time. We want it to be a continuously measuring so that’s why we need a solution with only one chart.

Best regards.

As you found it, it is not possible to change a chart from overlay to stacked during execution. Using 2 charts and making only one visisble is a simple workaround. To maintain the plots continuity, there are two possible solutions :
1/ copy the data from one chart to the other when switching charts
2/ simply plot the data on both charts at the same time.

Solution 2 seems to require more memory. However, a dual 1000 points (Dble precision floats) takes only 16 ko of memory space...
