Hi Bill,

Do you have a "getHTMLImageMap" line in your code? The tooltip is created by that line. If you remove that line, there will be no tooltip on the chart.

If your chart has multiple layers, and you want to disable tooltip only for an area layer, but enable tooltips for other layers, you can call Layer.setHTMLImageMap for the area layer to disable its tooltips. It is like:

myAreaLayer.setHTMLImageMap("{disable}");

Hope this can help.

Regards

It worked disabled the graph area. but my problem is the single data graph. I want it tooltip enable but not work.

Heres my code:

AreaLayer layer = c.addAreaLayer2(Chart.Stack);
                layer.setHTMLImageMap("{disable}");
                if (lblIndicator.Text == "HIGH")
                {
                    layer.addDataSet(LOW_LIMIT, Convert.ToInt32(RedBackColor.Replace("#", "0x"), 16), "").setDataName("");
                    layer.addDataSet(MID_LIMIT, Convert.ToInt32(YellowBackColor.Replace("#", "0x"), 16), "").setDataName("");
                    layer.addDataSet(HIGH_LIMIT, Convert.ToInt32(GreenBackColor.Replace("#", "0x"), 16), "").setDataName("");
                }
                else
                {
                    layer.addDataSet(LOW_LIMIT, Convert.ToInt32(GreenBackColor.Replace("#", "0x"), 16), "").setDataName("");
                    layer.addDataSet(MID_LIMIT, Convert.ToInt32(YellowBackColor.Replace("#", "0x"), 16), "").setDataName("");
                    layer.addDataSet(HIGH_LIMIT, Convert.ToInt32(RedBackColor.Replace("#", "0x"), 16), "").setDataName("");
                }

SplineLayer layer3 = c.addSplineLayer();
                layer3.addDataSet(ACTUAL3, 0x000000, "avg").setDataSymbol(Chart.Cross2Symbol, 14);
                layer3.addDataSet(ACTUAL3, 0x000000, "avg").setDataSymbol(Chart.CrossSymbol, 14);
                layer3.setLineWidth(3);
                layer3.moveFront();

Hi Bill,

As your probably know, the SplineLayer is for a spline curve. So there will be tooltip for the spline curve. For your "avg" SplineLayer (layer3), I do not see any spline curve, so there is no tooltip because there is no curve for the tooltip. (You need at least two points to draw a line or curve.)

If you want to display a single symbol, please use a scatter layer.

ScatterLayer layer3 = c.addScatterLayer(null, ACTUAL3, "avg", Chart.Cross2Symbol, 14, 0x000000);
layer3.addDataSet(ACTUAL3, 0x000000, "avg").setDataSymbol(Chart.CrossSymbol, 14);
layer3.moveFront();

Hope this can help.

Regards
Peter Kwan
