javascript - Ajax Google Visualization API Gauge with jquery -


I am looking to create a dashboard gauge that updates through Ajax. I have code below. I have Ajax code but I am unsure about updating gauges. Any suggestions? 

  google.load ('visualization', '1', {package: ['gauge']}); Google.setOnLoadCallback (drawChart); Function drawChart () {var data = new google.visualization.DataTable (); Data.addColumn ('string', 'label'); Data.addColumn ('number', 'value'); Data.addRows (1); Data.setValue (0, 0, 'Tempature'); Data.setValue (0, 1, 76); Var chart = new google.visualization.Gauge (document.getElementById ('liveTempChart')); Var option = {width: 340, height: 130, redfrom: 90, redTo: 100, yellow to: 75, pelato: 90, minor ticks: 5}; Chart.draw (data, options); }

Ajax code ...

(sensor as $ obj-> $ unit) {if ($ unit-> label == "Temp" ) {Reverse $ unit-> tempf "F"; }}

You can also use the same type of code for updates You need to create a new data table instance and then call the draw function of the chart (how you update for the first time). 

  var data = new google.visualization.DataTable); Data.addColumn ('string', 'label'); Data.addColumn ('number', 'value'); Data.addRows (1); Data.setValue (0, 0, 'Tempature'); Data.setValue (0, 1, 76); Chart.draw (data, options);

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
