Scatter Chart - One data point with value > 8 digits - YAxis data (too much)

[rob-connors]

SmartClient Version: v11.0p_2016-09-08/PowerEdition Deployment (built 2016-09-08)
Google Chrome Version 53.0.2785.143 m

Client recently upgraded from SmartClient V9. In that version:-

• A scatter chart, for example sake, has one data point 10,000 (US Million Dollars)
• YAxis data is in US Dollars (M) (11,000, 10,500 etc down to 0)
• A button is available that changes YAxis from US Dollars (M) to Us Dollars
• When button is clicked the chart refreshes and displays numbers on Y Axis. (11,000,000,000 10,000,000,000 etc down to 0) and point on chart with value E.G. 10,400,000,000

After upgrade,

• When there is a single scatter point
• And the number is longer than 8 digits "One data point - 9 digits.png"
• When the button is clicked to display as US Dollars
• Then the chart refreshes but the YAxis has too many data items making the YAxis and the chart canvas unreadable

When there is > 1 scatter data item the YAxis and data plot resolve OK. "Two data points - 11 digits and 5 digits.png"
When there is 1 scatter data item and digits lengths < 9 then OK "One data point - 8 digits.png"

Example

public class DynamicScatterChart extends FacetChart {

    class SimpleChartData extends Record { 

        public SimpleChartData() {
            
        }
          
        public SimpleChartData(int region, String product, Long sales) {  
            setAttribute("region", region);  
            setAttribute("product", product);  
            setAttribute("sales", sales);  
        }  
      
        public SimpleChartData[] getData() {  
            return new SimpleChartData[] {  
                new SimpleChartData(1, "Cars", 11000000000L),  
                new SimpleChartData(1, "Trucks", 50000)
            };  
        }  
      
    }  
    
    protected DynamicScatterChart() {
       
       setData(new SimpleChartData().getData());  
        setChartType(ChartType.SCATTER);  
        setTitle("Sales by Product and Region");  

        Facet groupingFacet = new Facet();
        groupingFacet.setValues(new FacetValue("sales"), new FacetValue("region"));
        groupingFacet.setInlinedValues(true);
        groupingFacet.setId("metric");
        
        Facet field = new Facet();
        field.setId("product");
          setFacets(groupingFacet, field);
    }
}

Looked at setExtraAxisMetrics and minDataSpreadPercent with no affect. Is there an Chart API setting required?
Has there been a change in how numeric data type conversions are handled? (Had to make code change to handle instance of Number in a grid)
Any ideas?

[rob-connors]

For a more succinct example, take the SmartGWT example from http://www.smartclient.com/smartgwte...erPlotCharting
Delete all the example data but leave one data item E.G. new ScatterPlotChartData(0.033f, 0.02f, "Moose")
Change the value for data item from float to Long E.G. new ScatterPlotChartData(0.033f, [COLOR=#c00000]10,000,000,000L[/COLOR], "Moose") and update constructor float to long
Run the code and you'll see the chart fill with grey lines because so many YAxis data points are plotted.

Am I missing something fundamental? Used to work for this application, after upgrade it doesn't.
The question is how to plot a single data point for a scatter chart where value is > 8 digits. Thank you.

We've applied a fix to SGWT 6.0p/SC 11.0p and newer branches, and it will be available in the nightly builds dated 2016-10-27 and beyond.

[rob-connors]

When will the next stable build be available? (We will need this for an upcoming release) The last stable build was 23/10/2016.
http://www.smartclient.com/builds/Sm...p/PowerEdition

After a retest with the 'd' build dated 27/10/2016 the fixes seem to resolve this issue and issue 241025. Thanks.
