I'm new to coding, and creating a line chart that is very simple.
What's not simple is, I want to have an image in each tooltip. I figured out how to have the same image in each tool tip, but I want a different image for each data point on the line. It doesn't need to change when I change the data, and the image has to be connected to the point on the line, and not just the value (for example day 3 might have a value of 10 and day 12 might also).
Has anyone done this, or does anyone have any ideas?

I am trying to add a small green arrow to a calculated field in Tableau. I cannot figure out for the life of me what to do. I have some images in my Tableau Repository, but the way my trainer is showing us is she is literally copy and pasting an image and it appears in the calculated field dialog box. I have tried to copy an image and paste it with no luck. Does anyone know how to do this? My trainer in the videos just does it like magic with no explanation of how to do it and it drives me insane. The code is very simple as I just want a green up arrow next to the growth percentage if its positive.
IF [Growth Percentage Profit] > 0
THEN "*green up arrow here*"
END
I exactly don't know how you are trying to do so.
but can get steps to do this from this link below.
may it could help you.

Earlier, I asked how to create "spectra" charts in Vaadin (see How to create a "spectrum" chart using Vaadin 14+). It turned out that one didn't actually need to create barcharts -- the only real need seemed to be to set the pointwidth to 1. (This solved the "very wide" widths lines when zooming.)
HOWEVER: I think there's a bug in vaadin charts when one has more than 1 series presents and when one zooms: the line moves to an inccorrect position on the x-axis (or the x-axis is no longer placed correctly.) Any thoughts on how to resolve? Here are two screenshots showing the problem. In the first one, only ONE series is visible and the line is at the correct x-axis point of ~598.36. In the second screenshot, though, (where the only change I have made is to enable the 2nd series), the line moves to an INCORRECT x-axis coordinate (it seems like it's ~598.25!!!).
One theory I have is that adding the second series somehow confuses the chart from determining the correct x-axes....maybe because each series has it's own x axis logic in some way? Not sure....(I'm using Vaadin 14 and I tested this both in my dev env and on production.)
Does highcharts support phase change lines ? It may be called multiple things but im looking to see if an X axis delineation line can be drawn in highcharts. It is used to specify a specific date in time where something in the environment changed. The chart reader would then look at that line and see if that change to the environment impacted the data represented by the lines in the line chart.
Anyone know if this can be done with high charts ? Sample image attached.
Great answer from Ondkloss: http://www.highcharts.com/docs/chart-concepts/plot-bands-and-plot-lines That page shows exactly what I was looking for.
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.

There are two examples in the demo that can help you on this:
