Hi,
I want to set the X’s label as a string of an Array, and this array is like: [2016-07-25, 2016-07-26, 2016-08-01, 2016-08-02, 2016-08-03, 2016-08-04, 2016-08-05, 2016-08-08, 2016-08-09, 2016-08-10] so I write the dataPoints: but the result shows:
only the X axis is totally wrong, but I’m pretty sure that the array data is right, So can you help me out? Thanks!
Ernest,
We observe that the array you are passing for labels are numbers and not string. If you like to display it as 2016-08-04 in label, store it as a string(“2016-08-04”). As its not a string, its considered as number and the result of 2016-08-04(2004) as been considered and assigned to label.
Change the array to [“2016-07-25”, “2016-07-26”, “2016-08-01”, “2016-08-02”, “2016-08-03”, “2016-08-04”, “2016-08-05”, “2016-08-08”, “2016-08-09”, “2016-08-10”]. And it works fine.
Vishwas R,
I’ve tried that way to fix it, but the result is: it just add “” to the wrong “numeric” X label. So, what can I do to let the system consider it as an String?
Or if the definition is wrong at the very beginning? Here’s my definition code:
it’s a jsp page and al4() is an ArrayList<String> type of Java, it stores bunch of date String: 2016-08-04, 2016-08-05, 2016-08-08, 2016-08-09, 2016-08-10.. with the combination code I pass the Java ArrayList item to the JavaScript Array item So can you give me some advise to fix it? Thank you!
It seems that the ArrayList you are storing is not string and result (2016-08-04 = 2004) is calculated at that instance and stored. Storing string within the array-list would solve the issue.
If your arraylist looks like al4 = [2016-07-25, 2016-07-26, 2016-08-01, 2016-08-02, 2016-08-03, 2016-08-04, 2016-08-05, 2016-08-08, 2016-08-09, 2016-08-10]; changing it to al4 = ["2016-07-25", "2016-07-26", "2016-08-01", "2016-08-02", "2016-08-03", "2016-08-04", "2016-08-05", "2016-08-08", "2016-08-09", "2016-08-10"]; would solve the issue.
al4 = [2016-07-25, 2016-07-26, 2016-08-01, 2016-08-02, 2016-08-03, 2016-08-04, 2016-08-05, 2016-08-08, 2016-08-09, 2016-08-10];
al4 = ["2016-07-25", "2016-07-26", "2016-08-01", "2016-08-02", "2016-08-03", "2016-08-04", "2016-08-05", "2016-08-08", "2016-08-09", "2016-08-10"];
It worked! With ur method, I checked my array. And I did store the String type to the ArrayList() al4, but when it pass to the JavaScript by using the method “out.print()”, it’ll get rid off the ” ” characters, so it should be like this ” out.print(“\””+al4.get(i)+”\””)”, then the “2016-xx-xx” will stored in the array of JavaScript.
Thanks for ur time!!!!!! :)
