QwtPlot x axis label

[ldg20]

Hello all,

I have a QwtPlot that is in real time and sliding. I want to have 400 x values visable. Initially the x axis was auto scaling and being deleted on the left and increasing on the right. This looks really bad. I want it to have the graph look like it is going off the page on both left and right.

I accomplished this with this function call:

plot->setAxisMaxMajor(QwtPlot::xBottom, 400);

Now the problem is I have 400 numbers marking each x axis tick. I have been looking around to no avail for a function to limit these numbers and only show maybe 4 with intervals of 100.

Can someone help me please? Thank you!
