2) One does not have to use .cht file. EspressChart can be split into two parts, like the enclosed E21.java
\nThe first part get data and create the chart with QbChart(), the second part use chart.export() to generate the PNG file. The API lines such as
\nIDataPointSet hDataPoints = chart.gethDataPoints();
\nhDataPoints.setColors(color);
\nCannot be sychronized individually as it was not executed sequentially but as part of the QbChart().
\nMost of the time is spent on chart.export (it takes seconds on PC and cannot be broken apart) and you may add java lines before or after to sychronize with your foreground.<\/p>\n","protected":false},"excerpt":{"rendered":"
