Code: Select all
chart.getAxes().getBottom().getLabels().setDateTimeFormat("d hh:mm");
chart.getAxes().getBottom().setIncrement(Utils.getDateTimeStep(DateTimeStep.ONEDAY));
chart.getAxes().getBottom().getTitle().setText("Date");
chart.getAxes().getBottom().getLabels().setRoundFirstLabel(true);
chart.getAxes().getBottom().setStartPosition(1);
com.steema.teechart.DateTime cd1 = new com.steema.teechart.DateTime(c1.getTime().getTime());
com.steema.teechart.DateTime cd2 = new com.steema.teechart.DateTime(c2.getTime().getTime());
chart.getAxes().getBottom().setMinMax(cd1, cd2);
c1 - 00:00:00 first date interval
c2 - 23:59:59 last date interval
My timezone +3h
I had like set axis line to 00:00
Sorry my English

Hi Demetrio,
Yes, it seems that the hour is not rounded or calculated correctly. So I've added this to the wish list to be fixed in future releases.
In the meanwhile you could force the 00:00 time to be shown as follows:
Code: Select all
chart.getAxes().getBottom().getLabels().setDateTimeFormat("d 00:00");

Set chart.getAxes().getBottom().getLabels().setDateTimeFormat("d 00:00"); is not correctly.
Just you changed label but not axis. I'l like that FIRST axis set to 00:00 and next... next... next
I use area chart with series.setStairs(true); and I set left border to 00:00:00(N - value) and right border 23:59:59( 0 - value) for my histogram
Code: Select all
com.steema.teechart.DateTime dd = new com.steema.teechart.DateTime(cStart.getTime().getTime());
series.add(dd, value);
dd = new com.steema.teechart.DateTime(cRight.getTime().getTime());
series.add(dd, 0);

How can I set first Label for DateTime axis?

I've decided my problem so TimeZone.setDefault(TimeZone.getTimeZone("GMT+0"));
I'm waiting your bug fix.
Best regards
Dmitry

Hi Dmitry,
I'm not sure to understand your problem. Is it possible that you are looking for SetMinMax axis function?
If not, could you please attach a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Yes I use function setMinMax(c1, c2) c1=00:00:00 c2=23:59:59
if set setRoundFirstLabel = true first vertical axis is 4:00:00 ( for my GMT +3)
if i set GMT+0 first vertical axis is 00:00:00 ( correct for me)

Hi Dmitry,
Then I'm afraid that you probably should translate your dates to GMT+0 before using them as dates.
