[regression] Dojox Charting: Gradient not working as expected in Dojo 1.6

[jeetesh_cn]

Please refer ​http://jsfiddle.net/qcQyT/. For Dojo 1.5 the gradients on the chart and the plot area are aligned.

However on Dojo 1.6, the gradients on axis are not aligned with the plotarea gradient. Also I get "Unexpected value NaN parsing x1 attribute." on console.

Confirmed on FF4. It looks like a logical problem rather than a browser/renderer bug.

Starting with 1.8 thanks to clipping you can fix that by removing any plot background and use only chart background to get the desired effect:

        dojo.require("dojox.charting.Chart2D");
        dojo.require("dojox.charting.themes.ThreeD");

        makeObjects = function(){
            dojo.query("button").style("disabled", true);

            var customTheme = dojox.charting.themes.ThreeD.clone();
            customTheme.plotarea.fill = null;
         
            customTheme.chart.fill = dojox.charting.Theme.generateGradient({
                                            type: "linear", space: "shape",
                                            x1: 0, y1: 0, x2: 0, y2: 100},
                                            "red", "blue");

            var chart1 = new dojox.charting.Chart2D("test1").
                    setTheme(customTheme).
                    addAxis("x", {fixLower: "major", fixUpper: "major", natural: true, includeZero: true}).
                    addAxis("y", {vertical: true, fixLower: "major", fixUpper: "major", natural: true, includeZero: true}).
                    addPlot("default", {type: "Markers"}).
                    addSeries("Series A", [{x: 1, y: 1}, {x: 2, y: 2}, {x: 3, y: 1}]).
                    addSeries("Series B", [{x: 3, y: 2}, {x: 4, y: 3}, {x: 5, y: 2}]).
                    addSeries("Series C", [{x: 5, y: 3}, {x: 6, y: 4}, {x: 7, y: 3}]).
                    render();

        };
        dojo.ready(makeObjects);
