FacetChart scaling issue

[checkpt]

Hi,

We are using a FacetChart to show a bar graph that represents a % value (0-100) on the Y-axis. We have recently upgraded our licence to version 6 from 4 to get the following functionality:

chart.setAxisStartValue(0.0);
chart.setAxisEndValue(100.0);

However, we see different behaviour for the Y axis scaling or ticks when the graph has data and when the graph has zero values. See the two screenshots for details.
Is there something else we need to set? E.g. can we specify the scaling?
SmartGWT version: 6.0p

Hi checkpt,

see this perhaps related thread. Are you using a newer version of 6.0p? You'll need to always tell your exact framework build date (I usually get it from the Developer Console).

Best regards

Hi Blama,

Thanks for the pointer it seems like a similar issue however, I have just downloaded the latest 6.0p version and still see the same issue.

Here is the version which exhibits the issue: SmartClient Version: v11.0p_2016-11-13/Pro Deployment (built 2016-11-13)

We're not seeing any problem. Can you provide some repro code? For reference, see the section titled, "Preparing a Standalone Test Case" here.

[checkpt]

Here is the example class BuiltInDS.java and ReceivingData.java. You will also need to add <inherits name="com.smartgwt.Charts"/> to .gwt.xml file.

The demo code will draw graph data on refresh for different conditions depending on the seconds provided by Date object. The two cases that show the issue happen at 0-20seconds past the minute e.g. from hh:mm:00 to hh:mm:20. The rest of the 10 sec intervals draw correct data.

We've applied a fix for this to SGWT 6.0p/SC 11.0p and newer branches. It will be in the nightly builds dated 2016-11-17 and beyond.

Hi Isomorphic,

Thanks for the quick turnaround, the fix looks good.
