How to achieve this Ui?

[thippu]

Hi,
I want to know how to do this,Image
It is a combination of QwtPlotCurve objects and I want to know how they combined together in a QwtPlotCanvas?

@thippu
Hi
are you sure its not multiple QwtPlotCanvas
on same form ?

QwtPlotCanvas (QwtPlot *=NULL)
seems to accept one plot.

[thippu]

@mrjj Sorry, I'm not sure.
can we able to set common x axis and different y axises to the each QwtPlotCanvas?
if yes, could you say me how to?
I'm searching for it.

[mrjj]

Hi
I think you can set it via setAxisScale
for each plot. and hence for each Canvas.

[thippu]

@mrjj okay, I will look at it, Thank you

[thippu]

@mrjj I want to make each QwtPlotCurve on the QwtPlot to have different Yaxis and share common x Axis O/P img

Can I get some thoughts from you? ,
what I'm thinking is either assigning each QwtPlotCurve to new QwtPlotCanvasand combining QwtPlotCanvas objects into single QwtPlot but I should have to share x axis among QwtPlotCanvas and different yaxis to each QwtPlotCanvas

[thippu]

@thippu Sorry, I said QwtPlotCanvas instead of QwtPlotCurve

[thippu]

I did search a lot on this, I got some information, I would like to share with you,
To achieve this kind of user interface, We can refer "plotmatrix" the QWT playground example

[thippu]

@mrjj Could you explain this more how to do in steps? please.
I have 32 QwtPlotCurves and I would like to put the same x axis for all but different y axis for each curve.

@thippu
Hi
But the sample already sets
setAxisScale
https://github.com/eiimage/qwt/blob/master/examples/plotmatrix/main.cpp

so which part is not working as intended ?

[thippu]

@mrjj I have developed this
There are 32 curves displaying and getting data from the socket and updating them.
I would like to achieve this:
If a user selects one of the curves by clicking on the curve and scrolls up(mouse scroll) selected curve should expand in Y(its own y) and if scrolls down it contrast.

@thippu
i think you can use
https://qwt.sourceforge.io/class_qwt_magnifier.html

[thippu]

@mrjj I mean selected curve y-axis scale should increase.
