AREA_RANGE issue - problem with points converting

[Adam Gzella]

Hi. We have recently switched to gwt-highcharts 1.7 and highcharts 4.2.5.

After a switch some arearange series stopped working. I have investigated the issue and I have found out that there is probably a bug in class BaseChart, method:
static JSONValue addPointScalarValues(Point point, JSONObject options, Series.Type seriesType)

There is no case for AREA_RANGE and default case is creating "x", "y" and "z" options. When you take a look into highcharts-more source code, arearange looks for options called "x", "low" and 'high". I was able to fix the problem by adding
case AREA_RANGE: at line 2717 in BaseChart.java.

Would you like me to contribute this fix, or would you be so kind to fix it?

For reference or others having this issue - we didn't wanted to mantain our own version of gwt-highcharts, so while waiting for a fix, I was able to do workaround. Instead of calling
series.setPoints(Point[], boolean)

do conversion of point on your own and call:
series.setPoints(JSONArray, boolean)

Code example (convertNumberToJSONValue is taken from BaseChart)

JSONArray array = new JSONArray();
int i = 0;

for(...) {
     JSONObject options = new JSONObject();
     options.put("x", convertNumberToJSONValue(rangeDataPoint.getTimestamp()));
     options.put("low", convertNumberToJSONValue(valueFrom));
     options.put("high", convertNumberToJSONValue(valueTo));
      array.set(i++, options);
}
series.setPoints(array, redraw);
