Hello,
I am working on Android Studio to plot a Plot.ly graph to indicate (X, Y, Z) points.
In order to plot Plot.ly’s graph with Android’s variables such as “int x,y,z =0;” I have to get the variable from Android/Java into Plot.ly’s Javascript codes inside, and directly into I couldn’t make this happen, and I need a help to set variables from Android to Plot.ly to draw a graph on Android’s webView.
My environment on Android’s MainActivity.Java:
WebView myWebView = (WebView)findViewById(R.id.webview);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView. * other necessary settings*
myWebView.loadDataWithBaseURL(“file:///android_asset/”, “< html >< head>< p >Plot.ly codes on here< /p >
< /body>>< /html>”, “text/HTML”, “UTF-8”, null);
I prepared a working demo graph on assets folder which known by Android as android_assets as different from a regular folder, but works almost similar on some points.
Between the HTML tags, I have the graph points to be declared as x, y, z:
< html> < body>
< script id=“plot-data” type=“text/json” src=“data.json”>[{“line”: {“color”: “black”, “width”: 3}, “mode”: “dashes”, “type”: “scatter3d”,
“x”: [1, 2, 3, 4, 5],
“y”: [0, 1, 2, 3, 4],
“z”: [1, 3, 5, 7, 9]}]
< /script>
< /body>< /html>
So, how can I change “x”, “y”, “z” ingredients by be able to define from Android’s java side?
Actually I used to divide the JSON part away from tags, but this didn’t work or I couldn’t do.
I mean <script src=“/aJsonData.json” …> < script> this code couldn’t be worked by me to provide from other file into it.
Also I tried inserting a “replace” function on javacript side to run from Android/Java but, this couldn’t change the Json file.
To sum up, I stuck at making graphics from providing x, y, z variables from Android/Java side into Plot.ly
Kind Regards.
