AmCharts for heatmap, black thing appears - charts

I'm using AmCharts, specially the heatmap, when there is only one value in the chart and put the mouse over it, the thing in the picture below appears at the left top corner.
I tried to look if there is a tooltip or something for mouse over but I couldn't access that thing

Fill letter with different color in certain direction

I need to create such animation in Flutter, in which by clicking on the letter(it can be svg, or ttf) it will fill with color in specific direction.
So, for example:
By clicking in letter, it should somehow be filled with color(let's say red), staring from top to bottom.
How it possible to do programmatically?
Have a look at the package: https://pub.dev/packages/animated_text_kit.
It provides Colorize and LiquidTextFill which can be used to achieve what you need.

Graphview legend position

I can place the legend top, middle, bottom, but its always on the right side of the graphview. How can I place it left side?
The most important problem that "too long" texts doesn't fit in the box, so the end of the text is outside the box / screen. I know I can change the text size, but I don't want to solve the problem in this way.
This solved my problem:
graph.getLegendRenderer().resetStyles();
Just called if I need to resize the legend box.
in the current version it's also possible to freely set the position of legend and also the width

How to check which place in panel was clicked? GWT

How can I check which place in Panel Was clicked? I know, I have this some functions:
getClientX, getClientY, getNativeButton, getRelativeX, getRelativeY, getScreenX, getScreenY, getX, getY
but how can I check which click Was near right side of panel and which was near left side of the panel?
I can't add to the Panel two div's with 50% width and detect in that way..
More info:
It's a lot of panels. I must do this in each of panel. I don't know how many panels we have. We have got a constans width of each panel = 400px.
Regards!
Assuming you're handling an onClick event or similar for a panel, you can get the cursor position with getClientX or something similar. Then just get the position and size of the panel and simply check what you're closet to; all elements are rectangular, so shouldn't be too difficult to just write four ifs for it.
The getElement() method will give you the panel's underlying element, so you may need to use that to get the exact size and position.

GWT dygraph not showing(collapses on top left corner)

I am trying to create a dygraph(using gviz) in a GWT application. The dygraph shows up as collapsed chart on the top left corner. i can see the slider in that corner.
If i resize the browser window, the chart shows up as expected.
I thought of calling chart.resize(width,height) but get an error chart has no method resize.
Any ideas how to fix it?
When you use GViz, you're most likely using a wrapper, not the real dygraph object.
Does "chart.date_graph.resize(width, height)" work for you?
