dashed ticklines/gridlines in flot

阅读更多关于 dashed ticklines/gridlines in flot

问题 I am pretty new to this flot API. I want to have dashed gridlines/ticklines instead of solid line both X-axis' and Y-axis'. Can anyone help me with this?? Thanks in advance! 回答1: I was able to produce dashed lines for the grid's markings by modifying the library. I'm currently using Flot ver 0.8.0 First I added a new attribute under grid (around line 400), just below the markingsLineWidth: markingsStyle: 'dashed' Since Flot is using canvas to render the charts, I added a dashedLineTo()

I'm working on moving a robot around a 2d grid room of 8 x 8, and one part is initialising the sensors which consist of the closest 5 tiles around the robot. self.sensors = [0 for x in xrange(5)] here I'm creating an empty of array of 5 elements. but when I attempt to set the value of sensors like this: if self.heading == 'East': self.sensors[0] = self.room[self.x, self.y-1] self.sensors[1] = self.room[self.x+1, self.y-1] self.sensors[2] = self.room[self.x+1, self.y] self.sensors[3] = self.room[self.x+1, self.y+1] self.sensors[4] = self.room[self.x, self.y+1] I get the error of 'list indices

Override standard method called by double click event in CRM grid.

阅读更多关于 Override standard method called by double click event in CRM grid.

Following situation in CRM 2011: My goal is to show several entities in one grid. Therefore we made a wrapper entity which links to the real entity (wrapper entity to entity A, B, C). When an item in A, B or C is created, also an wrapper entity item is created by a plugin. Like this I can have a grid, "mixing" all the entities, while in fact only show the items of the wrapper entity. But of course, if I do a double click or right click -> open in this grid, I don't want to open the wrapper entity item, I directly want to open the window of e.g. entity A item. Ribbon Button is no problem btw. I

WPF Grid - How to apply a style for just one column?

阅读更多关于 WPF Grid - How to apply a style for just one column?

问题 I have a WPF Grid with many rows and columns, all containing things like TextBlocks and TextBoxes. For this specific situation I want all the stuff in column 1 to have padding, and all the stuff in column 2 to be aligned right. It seems to be very non-WPF to have to set those properties on each item in the grid. I know I can create a style for all TextBlocks within a grid by doing something like this: <Grid> <Grid.Resources> <Style TargetType="{x:Type TextBox}"> <Setter Property=
