Hello, I put together few lines of code for showing temperature graph.
Everything works ok except xaxis is shown with all 46 numbers which
represent minuttes from now back. Is there any way to reduce shown nubers,
for example to show every tenth number?
Small piece of graph code is attached here to show issue.
With best regards, Vlado
