seems to work fine I think your issue is related to the scale fo your variables.
code :
tm_shape(df) + 
tm_fill("v2", title = "Change in V2",  
        breaks = c(-1000, -500, 0, 500, 1000, 10000, 30000), 
        border.alpha = 0, palette = "-RdBu")
tm_shape(df) + 
  tm_fill("v2", title = "Change in V2",  
          breaks = c(-1000, -500, 0, 500, 1000, 10000, 30000), 
          border.alpha = 0, palette = "-Greens")
tm_shape(df) + 
  tm_fill("v2", title = "Change in V2",  
          breaks = c(-1000, -500, 0, 500, 1000, 10000, 30000), 
          border.alpha = 0, palette = "PuBuGn")

hop of those help? For some reason $password (the one being sent form the form) is coming up blank. , Some things to consider:
code :
if(isset ($_POST['submit'])) {
if ($username&&$password){
if(!empty($username) && !empty($password)) {
while ($row = mysqli_fetch_assoc($result)) 
echo "
<div id='login'>
echo <<<EOL
<div id="login">

$error = NULL;

    $username = $_POST['name'];
    $password = $_POST['pw'];

    if (!empty($username) && !empty($password) {
        $qusername = mysql_real_escape_string($username);
        $qpassword = mysql_real_escape_string($password);

        $query = <<<EOL
FROM users
WHERE (username = $qusername) AND (password = $qpassword)
        $stmt = mysql_query($query);
        if (mysql_num_rows($stmt) == 1) {
             // store user details in session here
        } else {
             $error = "Invalid username or password";
    } else {
        $error = "Must specify both username and password";



<?php if (!empty($error)) { ?>
<h3><?php echo $error ?></h3>
<? } ?>

<form ...>
<table ...>
   <td><input type="text" name="name" value="<?php echo htmlspecialchars($name) ?>" /></td>
   <td><input type="password" name="pw" /></td>
<input type="submit" value="Login" />


How to display the Null values coming from the Table as blank in Textbox while load from the Gridview?

Any of those help If you are using DataSource controls, then set ConvertEmptyStringToNull="true" to your parameters
code :
        <asp:ControlParameter ConvertEmptyStringToNull="true" />
if (TextBox1.Text.Trim() = string.Empty)
        // pass the null value as parameter
        //com.Parameters.AddWithValue("@savePath", null);

How can I use sshpass with a blank password coming from a variable?

By : Ashish Kushwaha

seems to work fine I would like to write a script that can ssh into a linux target without any user interaction. The machine my script runs from as well as the targets that I'm trying to ssh into get reformatted every night so I can't use ssh-keygen (as far as I've seen) because I'm required to enter in the target's password manually when the keys are being set up. So instead I'm trying to use sshpass. Here's a simple example of how I'd like to use it: , Always quote your variables:
code :
sshpass -p "$pass" scp myfiles.tar.gz "$user@$host:/"
sshpass -p "$pass" ssh "$user@$host" "tar xvf myfiles.tar.gz"

hope this fix your issue Title pretty much says it all. , Use this one:
code :
=IFERROR(VLOOKUP(A8,'New Categories'!A$3:B19,2,FALSE), "") &
 IFERROR(", " & VLOOKUP(B8,'New Categories'!A$3:B206,2,FALSE), "") &
 IFERROR(", " & VLOOKUP(D8,'New Categories'!A$72:B$83,2,FALSE), "") &
 IFERROR(", " & VLOOKUP(E8,'New Categories'!$A$72:B$83,2,FALSE), "") &
 IFERROR(", " & VLOOKUP(F8,'New Categories'!$A$59:B$68,2,FALSE), "") &
 IFERROR(", " & VLOOKUP(G8,'New Categories'!$A$59:B$68,2,FALSE), "") &
 IFERROR(", " & VLOOKUP(H8,'New Categories'!$A$59:B$68,2,FALSE),"")

my crawl data not coming in json,csv its showing blank to me but in cmd its coming

fixed the issue. Will look into that further To have items exported (and to be able to get results when running scrapy crawl mydata -o items.json) you have to define items in your project as described in the docs.
After the item is defined you have to make sure you fill the item with values and return or yield the item. For a reference how to do this look at the docs here.
