I have installed Qt and now start programming.<br />
I wrote a program to draw graph by QwtPlot.<br />
so I dropped two QwtPlot widget on the form and separated them by vertical spacer, as I need to separate grid of different sizes to draw different curve.<br />
I introduced some points to be drawn and it looks ok when the x and y axis are enabled.<br />
but I like to disable the x and y axis  ui.qwtPlot1-&gt;enableAxis(QwtPlot::yLeft,false); and that makes the height of plot according to the highest y value of given point  and keeps changing as I change the points y value.<br />
how can I keep the grid and plotting area of each widget constant?<br />
many thanks<br />
