Re: THistogramSeries % Bar Width

Hello Marc,

thanks for the prompt and positive feedback. Happy to contribute - and after all, we're of course very interested to use the standard code base without having to merge any customisations of ours when installing a TeeChart update ... :D

Have a nice weekend,
Linus

Re: THistogramSeries % Bar Width

We experience a similar problem for TBarSeries where the bar widths are not aligned according to the preset BarWidthPercent when the x-axis is not set to automatic, i.e. does not show all existing values in the series. See the image below. wrong.png The settings are: BarWidthPercent set to 70% Botto...

Re: Changing the label of the axis ticks in event

Hi Yeray, what the user is able to do within our engine is to generate charts on a data set using "series generation blocks" that serve specific purposes (e.g. aggregating events (TDateTime timestamps) over time applying a rolling hour calculation). Those blocks dynamically create series-based data ...

Re: Changing the label of the axis ticks in event

Hi Yeray, thanks for bumping up the importance of the ticket! I fully agree that the data should be translated to seconds before populating the series. What I meant with "specific handling for those duration series" is that we need to Prepare the data by translating to seconds [OK, not a major probl...

Re: Changing the label of the axis ticks in event

Thanks Yeray, that sound like a good approach, at least for a static chart. We are developing an analysis suite for our simulation tools where charts are built dynamically and may contain multiple series, some of them date/time (or duration such as the "delay" I mentioned), some others displaying st...

Re: Changing the label of the axis ticks in event

Hi Narcis, thanks for your prompt answer. The problem of course is that when the initial LabelText denotes a positive value (as in my screenshot), the temp conversion into a TDatetime won't help. Even when adjusting the DateTimeFormat of the left axis to a fully qualified Date/Time format (such as '...

Re: Changing the label of the axis ticks in event

Hello, is there any news on this subject? We have a similar issue where having the value information delivered with the OnDrawAxisLabel callback would be really helpful: We frequently display time values (in the sense of a period of time, or a duration) in a chart, such as a delay. See the image bel...
