Hey everybody, I am dealing with the qcustomplot which is a very nice and handy library. Thank you for developing it. However, I am facing a problem right now, which I am unable to resolve (actually it should be very simple).
I am plotting data that need a logarithmic y-Axis and linear y-Axis into the qCustomPlot widget. Note, either the logarithmic or linear values are plotted.
Everything works fine until I once started plotting the logarithmic data first and switching back to the linear ones. Doing so, the y-Axis is not formatted correctly anymore, and I am really not able to change this behavior.
A snipped that created the plots:
void function plotData()
{
ui->myGraph->clearGraphs();
// A lot of code that prepares the data I want to code
...
// Logarithmic data
if (logarithmicData)
{
// Set all graphs
ui->myGraph->addGraph();
ui->myGraph->graph(0)->setData(x["anyField"],y["anyField"]);
...
// Setting y-axis to logarithmic scale and set number precision and style
ui()->v->yAxis->grid()->setSubGridVisible(true);
QSharedPointer<QCPAxisTickerLog> logTicker(new QCPAxisTickerLog);
ui()->myGraph->yAxis->setTicker(logTicker);
ui()->myGraph->yAxis->setScaleType(QCPAxis::stLogarithmic);
ui()->myGraph->yAxis->setNumberFormat("eb");
ui()->myGraph->yAxis->setNumberPrecision(0);
ui()->myGraph->yAxis->setRange(minY,1);
}
else if (linear)
{
// Setting all graphs
....
// Setting y-axis to a linear scale
// Here is the problem as I am not really sure about how to let the graph plot the
// y-Axis itself ... probably this peace of code it wrong
//
QSharedPointer<QCPAxisTickerFixed> fixedTicker(new QCPAxisTickerFixed);
ui()->myGraph->yAxis->setTicker(fixedTicker);
ui()->myGraph->yAxis->setScaleType(QCPAxis::stLinear);
ui()->myGraph->yAxis->setRange(minY, maxY);
ui()->myGraph->yAxis->setNumberFormat("g");
ui()->myGraph->yAxis->setNumberPrecision(5);
}
ui->myGraph->replot();
}
Picture 1: I directly plot the linear data (https://Holzmann-cfd.com/forum/PlotLinearFirst.png)
Picture 2: I directly plot the logarithmic data (https://holzmann-cfd.com/forum/PlotLogarithmicFirst.png)
Picture 3: I first plot the logarithmic data and then plot the linear data again (https://holzmann-cfd.com/forum/PlotLogarithmicAndThenLinear.png)
So the problem is, that I am unable to set the correct y-Axis settings for the linear plot. Any ideas are warmly welcomed.
