Following up on my question from yesterday:
SciChart - showing labels for all ticks
Thanks to the answer I was able to get the label density where I needed it. But I still have problems with label placement. As you can see in the screenshot, rotating the labels caused them to stick upwards into the graph. I need them below the axis. I've tried everything I could find in the API that I thought might help me:
a TranslateTransform - I tried moving both X and Y both ways. No
result.
VerticalAnchorPoint and HorizontalAnchorPoint - setting
VerticalAnchorPoint to Center actually moved the labels, but only by
3mm and in the wrong direction.
Horizontal/Vertical
Alignment/ContentAlignment - didn't do anything.
I've even tried
bloating the labels by appending a lot of spaces to the strings. A desperate attempt, I know.
Furthermore, the horizontal position of the labels is not correct either. In the screenshot you can see the first bump on the graph goes down on what looks like CF.02. But in reality it's set to CF.01. It would seem the labels are moved to the left of their corresponding tick. I need them to be displayed below the center of their respective tick, like the original solution.

In the SciChart's WPF Xaml Styling a Chart example there is a demonstration of how to rotate labels by changing the AxisBase.TickLabelStyle.
This uses RenderTransform to rotate labels by 15 degrees. However, if you use 90 degrees, the labels overlap the surface.
Changing the RenderTransform to LayoutTransform forces labels to be drawn in the correct place (below the axis).
You can read more about the difference between RenderTransform and LayoutTransform here.

In the attached Google charts Pie chart the labels fit well inside the segments. Determining the length of a bit of text in HTML5 canvas is easy enough - but how do you determine whether the label will fit into a particular segment (using trigonometry) ? As you can see on the image, two of the segments don't have labels inside the segment.
EDIT: Here's an example of what I have at the moment: https://www.rgraph.net/tests/canvas.pie/in-pie-labels.html
As you see the labels for the small segments overlap. What I'm after is a way to calculate whether there's enough space for the labels at the point where they're going to be rendered. If not, I can just not draw the label like in the example image above.
Could chord size be useful to do this?
Here's the forumulae for the chord size that I found via Google:
"Chord length using trigonometry = 2 × r × sin(θ/2); where 'r' is the radius of the circle and 'θ' is the angle subtended at the center by the chord."
I sorted it (in about one hour) after 3 days of trying to calculate it with trig by using the built-in context.isPointInPath() function...
Draw the text (transparent color) to get the coordinates (x/y/w/h) of it. You might be able to get away with measuring it to get the width and height.
Draw the segment in a transparent color and do not stroke or fill it. Also, do not close the path.
Test each corner of the text rectangle (formed the x/y/w/h that you got above) using the context.isPointInPath() function. If the function returns true for each corner of the rectangle formed by the coordinates of the text, then the text will fit into the segment.
Does anyone know how to put a margin at the top of the chart? I don't know if it's possible or a bug.
I already tried to modify the .margin({top: x, right: x, bottom: x, left: x}) but this is not the margin that I'm looking for. Setting the chart.yDomain() isn't good because I want the chart to rescale.
EDIT
My interest is that the linewithfocuschart rescale, not just force the domain.
The issue seems to be when the tooltip appears at the highest point in the chart. Maybe a bug, not really sure.
But here's one way of doing it, might not be the best way:
chart.forceY([0,160]);
By looking at your chart I'm assuming that 140 is the highest value in you chart. So I'm forcing the Y axis on the chart to show values between 0-160.
Update
Earlier I suggested the use of chart.forceY([0,160]); as a work around to adding margin to the chart top so the tooltips are clearly visible with the highest points. Although this approach only makes changes to the main chart and not the focus chart.
After some further investigation, I found out that you could use the following to rescale the chart and the focus:
chart.lines.forceY([0, yMax])
chart.lines2.forceY([0, yMax])
Here's a working example of using with a NVD3 lineWithFocusChart(). I have also got the yMaxdynamically in line 15 of my code.
I recently made a game with game maker and I've tried converting it to html5, but it's got some big errors... here is the game in html format: http://ivatrix.com/Game/index.html
First off, text is meant to appear in the top left like how you can see in this screenshot: http://gyazo.com/baa386fe06cfac9439c83b6e5192efd8 the text only appears after you create a combo.
Secondly, when you click on an orb it's meant to scale down to half it's size then scale up to 1.5x it's size, but instead it's shrinking until it's 1px large then infinitely increasing in size. Draw code is here:
if sl=1
{
if (s=0.6 or s=1) then d=d*(-1)
s+=d
if(frozen=1)
{
draw_sprite_ext(sprite_index,global.skin,x,y,s,s,0,c_blue,1)
}
}
And then there's other small errors like some text won't display, particle effects don't seem to draw, the game always returns saying there is no match on the board. That's all I've found so far.
Does anyone have any idea what I can do to fix this?
Thanks.
Since no one has provided an answer and I've found one myself, I'll put it up here so others in the same boat can benefit as well. Practically, the source of all my problems with floating point numbers being irregular, for example instead of it being 1 it could be 1.000000003, which meant if you were to check if that variable was equal to one, it would return false. Further information here: http://help.yoyogames.com/entries/77891197-HTML5-Issues-And-Differences
So for an example in my case, I changed the line
if (s=0.6 or s=1) then d=d*(-1)
to
if (s<0.6 or s>1) then d=d*(-1)
And now the problem is fixed.
I have a Stacked Area Chart in SSRS 2008 R2.
As you can see, the data labels are swallowed both left and right.
If I change the chart type to any area chart I have the same problem.
If I change to line type, it leaves space between the y axis and the chart.
Do you know any way around this?
I couldn't find a real solution to my issue. Playing with the Label, SmartLabels and NoMoveDirections properties didn't affect my chart at all - strange.
So I removed the axis and gave made the fill for the data labels as the corresponding areas. It looks like this:
Better than nothing...
By default, smart labels are placed in static positions. You can allow them to be moved by changing the NoMoveDirections properties. In your case, it looks like changing Left and Right to False should do the trick.
I'm trying to create a gray "frame" (see pic below) around a google map, to try to convey the concept of an area of focus, as oppose to a point (which is usually represented with a marker). Note that this is not an overlay, that is, the gray "frame" should not move when you drag the map.

It appears that only option is to "subclass" GControl to create a custom control. I have 3 questions
1) First of all, is GControl subclassing the best course of action?
2) In my example, the canvas (div) where map renders can change its size (i.e is not fixed width). Do I have to delete and add custom control when canvas changes size? See docs http://code.google.com/apis/maps/documentation/controls.html#Custom_Controls on how to create a custom map control.
3) Now, how to do it. Naively, I thought I could create a table with 3 columns and 3 rows, and set display: none for the cell in the middle. But that doesn't work. I've also experimented with clipping, that didn't work either. My css skills are quite lacking, so there must be way to do this more elegantly than adding four rectangular gray divs. If I wanted to add an inner border, with divs, I would need to paint 8 then. In a nutshell, what's the best way to create a "hollow" rectangle?
Thanks
P.S. This is my first entry to StackOverflow. Just discovered it. It's impressive how well SO is put together.
