RGraph: HTML5 Javascript charts library - Meter charts documentation

+ + + +

+ These are Meter charts. Similar to half the Odometer. The difference is purely visual, but may well be more suited to + a control panel type application. +

+ +

+ The example file is here. +

+ + 
+<script>
+    window.onload = function ()
+    {
+        var meter = new RGraph.Meter('myCanvas', 50, 100, 60);
+        meter.Set('chart.contextmenu', [
+                                        ['Show palette', RGraph.Showpalette],
+                                        ['Clear annotations', function () {RGraph.Clear(meter.canvas); meter.Draw();}],
+                                        null,
+                                        ['Cancel', function () {}]
+                                       ]);
+        meter.Set('chart.annotatable', true);
+        meter.Set('chart.label.position', 'inside');
+        meter.Set('chart.title', 'A sample measurement');
+        meter.Set('chart.title.vpos', 0.5);
+        meter.Set('chart.units.post', 'k');
+        meter.Set('chart.red.start', 0);
+        meter.Set('chart.red.end', 3);
+        meterSet('chart.yellow.start', 3);
+        meter.Set('chart.yellow.end', 6);
+        meter.Set('chart.green.start', 6);
+        meter.Set('chart.green.end', 10);
+        meter.Draw();
+    }
+</script>
+
+
