For some time did not play unity, or take a break to pick up and toss a bit. Recently upgraded to 4.6, the new version has been added to Unity's own unity system and looks much fresher. In the absence of Ugui days, it is good to have ngui with nature, but good and bad are relative, believe that unity official to come to the new UI system can be more excellent, easy to use.For the new UI system, many of the online Daniel has been out of a series of tutorials, I do not have too much energy to pond

different task expressions. The personal Gantt Chart allows you to intuitively know which tasks are to be performed in what time period, while the timetable provides more accurate time period data. In addition, you can directly update the task process in the schedule. 2. Make Excel2010 Open excel2010 and prepare the data to be sorted. Adjust the excel format. Generally, the

We can implement a custom effect that inherit

generate a scatter graph by using the data stored in MS SQL database. Second, set up the chart engine If you want to draw a chart in a asp.net application, you must have a suitable diagram engine. Asp. NET has a built-in graphics tool library, that is, System.Drawing namespace GDI +, can be used to create simple pie

Pie charts are one of the basic graphic types of Excel, and we usually use pie charts to represent each item's ratio, and sometimes we see a semicircle pie chart, but there's no such type in Excel, so how do we make it? 1, open

script file image.php, you use the GD library to dynamically output a pie chart by using the four steps of the image you described earlier. The code looks like this: Copy Code code as follows: Creates a canvas, returns a variable $image of a resource type, and opens a staging area in memory $image = Imagecreatetruecolor (100, 100); Create a canvas size of 100x100 Set the desired color in the

Introduced Matplotlib is Python's most famous drawing library, which provides a complete set of command APIs similar to MATLAB and is ideal for interactive charting. It can also be conveniently embedded in GUI applications as a drawing control. Its documentation is fairly complete, and there are hundreds of thumbnails on the Gallery page, which are available after they are opened. So if you need to draw some kind of diagram, just browse/copy/paste i
