Dygraph - hide axis labels when not showing data -

-

I do not know how to hide axis letters from the graph, when the visibility of all the data in the series show that the pivot is hidden The axes are shown without any problem, but when the two series (under my code) is hidden a special axis, the axis is visible and the label changes from 1 to 1/10 in increments of 1. I am grateful for any suggestions below that I am using the code: 

     
 
 
 I do not know how to do this through dygraphs API, but this One way to do this is to check your change event handler, which series is hidden and it determines which axes can be hidden then search all the text with the class - dygraph-axis-label-y and from them Repeat.  If their parent DIV is correctly aligned, then this is a Y1 label, if it is omitted, then this is a Y2 label. Update:  danvk commented that y2 labels have class  dygraph-axis-label-y2 , so I I am updating my answer to use the fact.  
  function changes (L) {chart .setVisibility (el.id, el.checked); Var y1vis = ($ ("# 0: checked"). Length + $ ("# 1: Checked"). Length) & gt; 0; Var y2vis = ($ ("# 2: checked"). Length + $ ("# 3: Checked"). Length) & gt; 0; If (y1vis) {$ (".digraph-axis- label-wi: not (.grig-axis-label-y2)"). Show (); } And {$ (".digraph-axis-label-y: no (ograph-axis-label-y2)"). Hide (); } If (y2vis) {$ (".digraph-axis-label-y2"). Show (); } And {$ (".dygraph-axis-label-y2"). Hide (); }}    function change (L) {chart.setVisibility (el.id, el.checked); Var y1vis = ($ ("# 0: checked"). Length + $ ("# 1: Checked"). Length) & gt; 0; Var y2vis = ($ ("# 2: checked"). Length + $ ("# 3: Checked"). Length) & gt; 0; If (y1vis & y2vis) {$ (".digraph-axis-label-y") Show (); } And {$ (".dygraph-axis-label-y"). Each (function () {// var IsY1 = $ (this) .Parent (.css ("text-align") == "right"; // var isY1 =! $ (This) .hasClass (" dygraph-axis-label-y2 "); if (IsY1 & amp;; y1vis) {$ (this) .hide ();} if (! ISY1 & amp;; y2vis) {$ ( This) .hide ();}}); }}

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
