Charts not automatically rendered

When booting my Pi3, Openplotter automatically starts up OpenCPN. However only chart outlines are rendered on the screen, not the full charts. How can I set up OpenCPN so that the charts are rendered automatically?


Is it possible to make OpenCPN ALWAYS render full charts i.s.o. chart outlines?



Thanks!

Zoom in. If the quilting still does not start to render charts, click on some of the colored rectangles/ovals in the chart bar on the bottom of the screen.

Thanks Nohal,


Any settings to automate the zoom-in and click chart bar action?


Furthermore I noticed that single left clicking the zoom buttons in the tools bar, only zooms in or out in extremely small steps. Double clicking zooms in or out in very large steps. Is it possible to set the step size for zooming to a more convenient value?


Thanks again.

It's open source software. You can change anything you want.

There is no need to automate anything, OpenCPN remembers your last viewport and restores it the next time you start it. At least on all my machines.

You can sure try changing the Smooth panning/zooming setting in the Toolbox->Display->General tab. Or do not use those Toolbar buttons and zoom using your pointer device, eg. a mouse wheel or keyboard. There is no way to adjust the steps. I haven't clicked any of those buttons for years myself.

Try holding "alt" while zooming if it's too fast.
