I have draggable line serie on my chart. Is there any way to allow set only integer values when dragging? Some kind of snap or constraint only to integer numbers.

link : D3 Charting Tool: How to add label at right of target line (additional horizontal line) in column chart
I implemented the graph through this link.
The problem is that if there are multiple graphs and the y-axis values are different at the same height, if the horizon value is 10px, then 10px is output regardless of the y-axis range.
If i want to add horizontal lines according to the y-axis range, I'd like to know a solution.
I would like to have a graph in amCharts where the x-axis is the time and bars represent in different colors and heights representing events in time. Now I would like to have that zoom-able so that captions in the bars only appear if there is enough space to display them.
In my example picture the caption is not displayed on the magenta bars:

I would try to do this with a date-based serial chart. You could try using a separate step line for each column with fillAlpha set to 1 or one step graph and use fillColorsField and set color in your data at a position where color should be changed. As for labels, it's more complicated - graph has hideLabelsCount property, but it will show/hide all labels once certain zoom level is reached. You could try employ labelFunction of a graph and usesome function which would set label to empty string, depending on zoom level.
I'm Ctrl dragging from one UILabel to another to set a vertical spacing and I get the following dialog:
What does this dialog mean?
How do I set a vertical spacing between the 2 UILabels using this dialog?
Apparently, you already have created a vertical spacing constraint. That's what the dot (•) next to Vertical Spacing means.
If you were starting from scratch, you would select Vertical Spacing. That would create a constraint which maintains the current vertical spacing between the labels as they are laid out on the canvas. You could then select that constraint and modify it, if you want. You can find the constraint in the document outline or you can look at the Size inspector for one of the affected views.
In general, that window lets you create one or more constraints based on the current layout of the designated views. Clicking on one of the items creates that one constraint. Shift-clicking on an item selects it and leaves the panel up so you can select more. When you've selected all that you want, click outside of the panel to create all the specified constraints.
Choosing "Left" creates a constraint relating the left (or leading) side of the views, with a constant for their current distance. Similar for "Center X" and "Right", except relating different attributes of the views.
Equal Widths creates a constraint relating the widths of the views, with a constant for the current difference in their widths. Similar for Equal Heights. Aspect Ratio creates a constraint relating the width of one to the height of the other (it makes most sense when you create a constraint from a view to itself).
I have a bar graph where each bar represents a value for a specific date. Since the data does not occur equally spaced in time, I am using an incrementing integer for the X value, and putting the date in as the label value. Some bars do not have a date (the label is empty). The graph shows empty label values as label boxes containing "0", rather than hiding the label boxes for those bars entirely (which would make sense, since the labels are empty, not "0"). Is there any way to instruct TeeChart to remove those unnecessary and confusing label boxes?
I want to draw marks in custom positions, but what is the best event or procedure for it?
Because if I process them in OnAfterDraw event my chart will be rendered twice and etc.
Is it possible to set the position before drawing the chart?
You need the series to have been drawn at least once (so its marks' positions have been populated) to be able to modify these positions.
