c# - MS Charts: Getting the real InnerPlotPosition? -

-

When creating a chart using Microsoft charts, I need to get the correct position of the grid on the chart.

- As I think - it can be obtained by the interpretation, however, when using this property, I get the following rectangle: inner potion

It looks rectangular to scale with chart size; When the size of the chart changes, the rectangle decreases, but still remains outside the grid on all the edges. I have tried to add and multiply the size with a constant, but there is no single stable work for all sizes.

So, just to make it clear, what I want is the outer black rectangle on the grid Is there any way to do this?

(I was thinking of scanning pixels from the edges, and was detecting the first black pixel in every direction, but this disturbance looks like a hack.)

I finally found a solution that works: 

  chartAre = chart.ChartAreas [0 ]; Double X1 = a.AxisX.ValueToPixelPosition (a.AxisX.Minimum); Double X2 = a.AxisX.ValueToPixelPosition (a.AxisX.Maximum); Double y1 = a.AxisY.ValueToPixelPosition (a.AxisY.Maximum); Double y2 = a.AxisY.ValueToPixelPosition (a.AxisY.Minimum);

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
