Export utility not including changes made to the data after render time about highcharts

[TorsteinHonsi]

For adding series, this issue can be worked around by adding the series options to the chart options object in an event handler. See http://jsfiddle.net/qX6Kf/2/

chart: {
    renderTo: 'container',

    // start workaround
    events: {
        addSeries: function(series) {
            this.options.series.push(series.options);
        }
    }
    // end workaround
},

...and with series.remove:

Added feature where exported image reflects updated data in the chart. Closed by 9bd4aad.

The same problem applies for setCategories() method. New categories don't appear on exported charts.

Same problem with setTitle(). Click the Set Title link and see the title change on the chart. Then click export button and you see it renders the old title without the new title and subtitle.

I needed the ability to export categories that were added after initial chart creation by setCategories(), so I added the some code into the loop that sets the extremes of the axis to also loop through and set the categories of the axis.

            // reflect axis extremes in the export
            each(['xAxis', 'yAxis'], function (axisType) {
                each(chart[axisType], function (axis, i) {
                    var axisCopy = chartCopy[axisType][i],
                    extremes = axis.getExtremes(),
                    userMin = extremes.userMin,
                    userMax = extremes.userMax;

                    if (userMin !== UNDEFINED || userMax !== UNDEFINED) {
                        axisCopy.setExtremes(userMin, userMax, true, false);
                    }

                    // addition to include categories that were set by setCategories
                    if (axis.categories) {
                        var categories = [];
                        each(axis.categories, function (category, i) {
                            categories.push(category);
                        });
                        axisCopy.setCategories(categories, true);
                    }
                });
            });

Demo for the setCategories case: http://jsfiddle.net/highcharts/WMtv6/

1. Click the set categories button
2. Click Export chart button
3. Observe that the downloaded image doesn't reflect the changes.

You have not resolve this problem?

Here's a little workaround that you can use:

I have found an issue with the workaround. If you click "Set Title" more than once, you lose the formatting on the chart title. I am also seeing this in my application when trying to use the workaround. Does anyone have any thoughts on avoiding this?

[TorsteinHonsi]

I've updated the workaround, and also fixed the issue in the core.
