MouseOver errors on chart hiding

[k2xl]

So I'm getting strange bug.

I have three charts to display. My tooltips show nicely on each point (showing the y value of each of the three graphs). However, if I hide one of my graphs, then I begin getting the following highstocks error:

Uncaught TypeError: Property 'onMouseOver' of object #<Object> is not a function
in the highstocks file line 6882

Here is the code if interested:

Code: Select all

// separate tooltip and general mouse events
            if (hoverSeries && hoverSeries.tracker) { // only use for line-type series with common tracker

                // get the point
                point = hoverSeries.tooltipPoints[index];

                // a new point is hovered, refresh the tooltip
                if (point && point !== hoverPoint) {

                    // trigger the events
                    point.onMouseOver();
highcharts.js:6882Uncaught TypeError: Property 'onMouseOver' of object #<Object> is not a function

                }
            }



Error happens on point.onMouseOver... says point doesn't have onMouseOver??

I'm using latest Highstocks (1.01, one that released on 10/25/11).

Any ideas?

I'm receiving the same error if I call setExtremes on the chart's yAxis. Tooltips work fine after the chart is rendered, then I click a button that then calls setExtremes() ... tooltips no longer work and I see this same error in the console.

[josephruscio]

If rather than using setExtremes() I just directly set chart.yAxis[0].options.min/max ... this doesn't happen. Looks like setExtremes() sets userMin/Max, which I assume is then accessed when the series is actually rendered. Something in that code path must be affecting the Point.onMouseOver attribute.

I get the same error with this code:

Code: Select all

plotOptions: {
         series: {
            events: {
               legendItemClick : function(e){
                            var chart = this.chart;

                  var x_extr = chart.xAxis[0].getExtremes();
                  chart.xAxis[0].setExtremes(x_extr.min, x_extr.max);
               }
            }
         },

Does anyone has workaround?

Add a sample. Get error with tooltip when hide/show series by legend.

Do you consider this fixed with yesterday's bugfix commit?

I had the same problem but it's fixed in the testing version of Highstock. But now another bug occurs for me. When I hide/show the series from the legend (also when I zoom-in by drag and drop) some other points stays after these actions. You can try it here: http://jsfiddle.net/Vangi/F3YqY/9/

Yes, you're right Slawek. This is the same problem like my. Thank you for the link.

Hi, maybe bug come back with HighStock ver 1.1.3
Please see my code http://jsfiddle.net/boykocodon/VhyQc/9/
I zoom manual, and then click button Set.
Nothing happen, so function setExtremes not work correctly.
Please help me, thanks!

We had the same problem here. This error occurs after we update HighStock 1.1.3

I don't see any problem in your fiddle "set" button works exactly as you defined, it set extremes to the same as visible. Here you can find updated example: http://highcharts.com/jsbin/anaqiy/edit

Well, i say after zoom manual, press button "Set", not only click button "Set".
So I still see problem in my fiddle.

I did this. But as I check this:

Code: Select all

$("#button").click(function(){
        var ext=chart.xAxis[0].getExtremes();
        chart.xAxis[0].setExtremes(ext.min,ext.max);
    });

After button click you read current extremes (and current zoom level), then you set it as a new extremes which are the same. Now the main question is what you need to do?
