ALT+ScrollWheel causes loss of focus #436
Description
Describe the bug
After you zoom vertically, using alt+scroll-wheel, zooming horizontally using ctrl+scroll-wheel doesn't work, until the user clicks in, or pans the graph.
To Reproduce
Press alt and scroll to zoom in/out vertically. Release alt, then press ctrl and scroll to zoom horizontally. => You'd expect the graph to zoom horizontally, but nothing happens.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
double[] dataX = new double[] { 1, 2, 3, 4, 5 };
double[] dataY = new double[] { 1, 4, 9, 16, 25 };
formsPlot1.plt.PlotScatter(dataX, dataY);
formsPlot1.Render();
}
}
