Seeking ConnectIQ API for Pen Style to draw dashed lines, other graphing related operations.

Former Member over 5 years ago

Hello - The spec for one of our views shows a graph with dashed lines for thresholds. I'm doing the following to draw a solid line:

dc.setColor(Graphics.COLOR_RED, Graphics.COLOR_TRANSPARENT);
dc.setPenWidth(2);
dc.drawLine(hiThresholdX1, hiThresholdY, hiThresholdX2, hiThresholdY);

I grepped all the samples for anything related to setting the Pen Style to dashed rather than solid with no luck. Also, scanned the APIs but again no luck.

I can draw many short lines along the vector to create a dashed line appearance but wonder if I'm missing something that is readily available.

Any insights are most welcome. Thanks, Matthew

If you want dashed lines, that is something you need to do yourself. You could use an image and just draw that image instead of a bunch of drawLines

Appreciate the quick reply. Good to confirm I wasn't missing something obvious. Always wanted to do my own dashed lines. ;} Thanks, Matthew

function drawDashedLine(dc, graphLeft, graphRight, thresholdY) {
var dashLen = 8;
var x = 0;
for (x = 0; x < graphRight; x += dashLen*2) {
dc.drawLine(x, thresholdY, x+dashLen, thresholdY);
}
// dc.drawLine(graphLeft, thresholdY, graphRight, thresholdY);
}
