We've made a fix to resolve issue #2 to SGWT 5.0p/SC 10.0p and newer. It should be in the nightly builds dated 2016-03-31 and beyond.

As mentioned earlier, those gaps are by design, to mark the locations corresponding to the axis labels. However, they should only be in Area charts, not Line charts. We see the behavior you mention for Line charts and are investigating.

There are also gaps in the default chart: just open the link:

Isomorphic?
Were you able to reproduce Issue #2?

Browser Firefox 45.0
OS: Apple 10.11.2

Issue #3 is corrected, thanks.

For issue #2: I was using smartgwt 07.03.16 power (5.0p). (And now using 20.03.15 5.0p and it's the same)
No, i am NOT rebuilding the showcase with changes. I just opened the showcase, changed (with right-click in the context-menu) the chart type to Line.

So, step by step:
Open http://www.smartclient.com/smartgwte...tockPricesZoom with Firefox 45.0
Right click
Change chart type to line
you should see the gaps in the zoom-chart

In your smartclient Example (http://www.smartclient.com/#stockPriceCharting) it is the same: Right click, change chart to "Line", and then I see the gaps.
If I change in the stockChart.js "Area" to "Line" and then "try it", then I DO NOT SEE THIS GAPS. So it seems only to happen when right clicking the chart and changing the chart type from the context menu.

We've committed a fix for the "zero problem" (issue #3) to SGWT 5.0p/SC 10.p and newer. It will be available in the nightly builds dated 2016-03-12 and newer.

As far as issue #2, we're not able to reproduce it, and you've not provided your complete version info. From the New Topic page:

Be sure your post includes:

1. The *complete* SmartGWT or SmartClient version from the lower left-hand corner of the Developer Console (see FAQ for how to open Developer Console), for example, "v10.0p_2015-06-18/PowerEdition Deployment"

In "Area" mode, there should be lines or gaps in the chart at the bottom - these correspond to the locations of the x-axis labels and help the user judge data location. In "Line" mode, these should become dotted vertical grey lines, and indeed that's what we see when we rebuild the showcase ourselves.

We don't see gaps in "Line" mode as your screen capture shows. When you say,

I see similar effects in your showcase when changing the diagram-type to line:

http://www.smartclient.com/smartgwte...tockPricesZoom

presumably you mean you rebuilt the showcase yourself with said changes, since the online version can't be modified. What browser and OS are you using?

If you're comfortable checking the SmartClient Framework, go to http://www.smartclient.com/#stockPriceCharting in the same browser, and change chartType: "Area" to chartType: "Line" in the stockChart.js tab and click "Try It". Do you see the problem from your screenshot, or the grey lines I mentioned near each x-axis label?

[edulid]

The 2) issue can be reproduced in your showcase: http://www.smartclient.com/smartgwte...tockPricesZoom (http://forums.smartclient.com/forum/...9-diagram-zoom)

We see the problem causing the 3rd issue and are testing a solution - the fix may solve more than just that one. We'll update this thread as more becomes known.

[Isomorphic]

I think this is a new issue, since in my examples, the data was truncated in the zoom-area, and in your examples the data was truncated in the original chart. But yes, this is a similar issue !
So there seem to be 4 issues all similar but different:
1) Data is truncated in the zoom chart when going from zero http://forums.smartclient.com/forum/...632#post235632
2) Data is truncated in the zoom chart (but not going from zero) http://forums.smartclient.com/forum/...40#post2356403)
3) Zoom-Area completely ignores a part of the original data http://forums.smartclient.com/forum/...643#post235643
4) Original chart is truncated http://forums.smartclient.com/forum/...645#post235645

Isomorphic please take a look at these 4 issues

We see the repro code for the 3rd issue. For the others, can you provide repro code or indicate what sample was used?

[edulid]

I was experimenting and I get another problem. See the attached screenshots.
As you see, the first seems correct, but the second not. The original chart and the zoom-region are totally different. So what is correct? The original chart? The zoomed chart?

[edulid]

Another example of truncated values in the main chart, please refer to the attachment.

Hi Isomorphic,

I can reproduce using the online sample. See attached screenshot.

EDIT: Seeing the crossposts: This seems not to be value-near-0-related.

[edulid]

While experimenting with your examples and changing the chart to type="LINE" and changing some values to be "zero", I see a similar problem with your zoom. Maybe it is another issue, maybe it is related, so here it goes:
The two arrows are showing the same point of time in the attachment (screenshot).
But the zoom is not accurate: while the sample decreases after the arrow to zero, the zoom increases !!!!! Maybe therer is an issue with "zeros" as my original problem was also related to the "zero" value.

Testcase:

@Override  
    public void onModuleLoad() {  
        final FacetChart chart = new FacetChart();

        final DynamicForm chartSelector = new DynamicForm();  
        final SelectItem chartType = new SelectItem("chartType", "Chart Type");  
        chartType.setValueMap(

                } else if (ChartType.BAR.getValue().equals(selectedChartType)) {  
                    chart.setChartType(ChartType.BAR);  
                } else if (ChartType.COLUMN.getValue().equals(selectedChartType)) {
