Sorry to bother "again", we have a couple of important questions, we noticed that some of the X labels disappear randomly, my understanding is that sometimes, when we don't have space, labels should hide but this behavior is happening even if there's space, we have version 10.3.1 of Gantt, please check the following for better understanding:
and also...
Now we would like to ask if there's a solution for this? or an update? also would like to ask something related... as you can see in the images, we have divided the X into 3 lines, years, quarters and months, is there a way to have the months 3 letters as shown when there's enough space and show only the month initial when the space is reduced?
Thank you for any help you may bring!
You may try setting the padding to 0 or to set allowOverlap=true

I wanted to ask how to increase the values of the axis to display data correctly?
I tried searching the teechart options but with no luck.
In this case, you should either
use one more digit in the number format (0.0000) on the left axis, or
increase the distance between the labels on the left axis.
In a comment to the question, the OP confirmed that the number format should be changed.
To do this at runtime, you can do
MyChart.Axes.Left.AxisValuesFormat := '0.0000';
It is also possible to do this at design-time.

Looking for some help or to be pointed in the right direction. Been stuck on this for a while and the main issue is I don't even know where to start. I am sure there is a solution but my brain will not see it.
To use as an example I have a table that shows monthly results for multiple different areas:
What I want to do is in the gap along side each number is show an increase, decrease or no change, using up arrow down arrow and square. That I can do using conditional formatting my issue comes with the fact that I also want it to be multiple Colours. So it will take into account increase and decrease and whether they are in target.See below:
Atm I am copying and pasting each month. But having it automated would be amazing. The outcome would hopefully look like this:
I am hoping there is a way that I can do two things compare to the previous month and then check it against my table to see where it sits then display the appropriate symbol.
Thank you in advance for any help or a place to start.
So extremely easy to figure out once I looked at it in a simplistic way.
Firstly, I used: =IF(-SIGN(E26-G26)= 0, "n", IF(-SIGN(E26-G26)=1, "é", IF(-SIGN(E26-G26)=-1, "ê","")))
To compare the current number to the previous number and get a 1, 0 or -1 depending on if it had gone up down or stayed the same, using this it either displays é, n or ê. I then set the font on these cells to Wingdings. so they become up arrow, down arrow and a square.
Then I use conditional formatting to colour it based on the adjacent cells value.
No need for a long, complex formula
=IF(A2>A1,"t",IF(A2<A1,"u","v")) - set the font to Marlett

After I apply erosion+dilation it looks like this:
erosion+dilation applied
Finally I find contours for further segmentation. Obviously, I can cut "1" from the image as it's not connected with other digits. But how can I separate 5 from 7, and 7 from 8, and two zeros on the right in this case? On the first link I see that 5 and 7 are not overlapped, this way i can somehow remember it and use after applying erosion+dilation. Maybe drawing white vertical line. But still i have problems with 7 and 8.
Any help and advises are appreciated!
What you need is a technique called skeletonization, https://en.wikipedia.org/wiki/Topological_skeleton
It will help in this specific case.
In a candlestick graph i am building, the latest bar is cut-off partially such that even the bar is not visible. Thus it's difficult to judge the high and low by seeing the bar.
I'm unable to post a pic now but it's like the last rectangle being cut in half.
I'm tried a lot of options in the api but can't figure out why this is not showing correctly. The chart margin and axis offset options havent' helped. Is there a way i can set the series margin from the plot area so that it displays right.
For this problem, the best solution is to insert a dummy series which should be hidden from every aspect of the chart. So try this, insert a dummy series from the last point of the data series to some extra buffer(as per need). Then remove this series from the chart by explicitly removing it from the legends (using showinlegend),chart(setting linewidth to 0) and from tooltip by having a check in formatter. Hope this solves your problem.
I had the same problem and couldn't figure it out, because no matter how I changed the xAxis.maxPadding or changed the xAxis.max, it would always cut off the last candlestick when I clicked on the range selector.
To solve it, (hack) I just added an extra data point in my series and set it 1 day past the last day and set all values to null.
Without any code or a pic, it's hard to tell the problem, but it sounds like you need to use the max padding option. http://api.highcharts.com/highcharts#xAxis.maxPadding. You may also want to look at endOnTick as well as whether you are setting max on the axis.
I am using the TeeChart VCL Delphi module. I am trying to plot a candlestick chart. I have the following questions:
When I run the code it shows me the last date data on the right hand side. However, the y-axis is not automatically scaling at all. If I scroll backwards, it automatically adjust the y-axis scales. However, if I go far to the right which is the end, it does not auto-scale the y-axis anymore. What am I doing wrong?
The x-axis is the days of the week. However, I have no data for the weekend. It shows as empty space. How do I remove that?
How do you change the cursor so it shows the date/time for the X,Y you choose?

What about setting the Y axis (left axis) to be automatic? For example:
Chart1.Axes.Left.Automatic:=True;
A more drastic solution would be also forcing the chart to repaint after adding each point.
Series1.Add(value);
Chart1.Draw;
If any of that helps please send us a simple example project we can run "as-is" to reproduce the problem here. You can attach your files here.

You should do as in the All Features\Welcome!\Chart Styles\Financial\Candle (OHLC)\Axis Labels no Weekends example in the new features demo. This demo is included with registered and evaluation versions. Otherwise you can download it here.
