Axis Tick and Label !

[huyhoangfool]

Is your question about how to align the ticks to the inner side of the plot ?

Hi Uwe,

Yes, that's my second question.

My first question is why the tick at the maximum value of the x axis doesn't display when i disable the label.

Can you please give me any hint ?

Thanks

In general I don't see a reason for this. Without running some code it is hard to say more.

Hi Uwe,

Thanks for response.
The code is done as following:

QwtPlot *myPlot = new QwtPlot;

//Set Axis Scale
myPlot->setAxisScale(QwtPlot::xBottom, 0, 12);
myPlot->setAxisScale(QwtPlot::yLeft, 0, 120);

//Set Axis Title, Set Max Minor, Medium, Major
...

//Disable Label Component
myPlot->axisScaleDraw(QwtPlot::xBottom)->enableComponent(QwtAbstractScaleDraw::Labels, false);

When i use this line "myPlot->axisScaleDraw(QwtPlot::xBottom)->enableComponent(QwtAbstractScaleDraw::Labels, false);", the tick at the maximum value of x axis (value: 12) doesn't display.

If i set the pen width of the ScaleDraw to 2, that tick will display. But, it's very ugly.

Looks like a bug in the layout code of QwtScaleWidget to me. Maybe subtracting one pixel from length in QwtScaleWidget::layoutScale() is the necessary fix.
