  1. First value in dataseries duplicating in msline chart PHP JSON

    waflfootyfacts replied to waflfootyfacts's topic in FusionCharts and PHP

    Can anyone provide me with some assistance?
  2. I am trying to create an msline chart using PHP and JSON to display data from my SQL database using the Fusion Charts Factory Sample database as my guide. In both cases (with Factory Sample data and my own data) the first value in each data series are duplicated as the first and second data point, and the last value does not appear on the chart. My SQL query returns the following datasets $strQueryCategories Game R9,2015 R9,2015 R20,2015 R20,2015 EF,2015 R1,2016 R1,2016 $strQuery​Data Team Game Total Claremont R9,2015 60 Claremont R20,2015 60 Claremont EF,2015 61 Claremont R1,2016 110 East Perth R9,2015 21 East Perth R20,2015 70 East Perth EF,2015 93 East Perth R1,2016 34 // Form the SQL query $strQueryCategories = "SELECT CONCAT(RoundNo, ',',Season) AS Game FROM MatchDetails WHERE (Team = 'East Perth' OR Opponent = 'East Perth') AND (Team = 'Claremont' OR Opponent = 'Claremont') AND Season > 2014 ORDER BY GameID ASC"; $resultCategories = $dbhandle->query($strQueryCategories)or exit("Error code ({$dbhandle->errno}): {$dbhandle->error}"); $strQueryData = "SELECT Team, CONCAT(RoundNo, ',',Season) AS Game, Total FROM MatchDetails WHERE (Team = 'East Perth' OR Opponent = 'East Perth') AND (Team = 'Claremont' OR Opponent = 'Claremont') AND Season >2014 ORDER BY Team, GameId ASC"; $resultData = $dbhandle->query($strQueryData)or exit("Error code ({$dbhandle->errno}): {$dbhandle->error}"); if ($resultData) { $arrData = array( "chart" => array( "caption" => "Head to Head Since Start 2015", "subcaption" => "Scores For & Against", "theme" => "fint" ) ); $arrData["categories"] = array(array("category" => array())); if ($resultCategories) { $controlBreakValue = ""; while ($row = mysqli_fetch_array($resultCategories)) { if ($controlBreakValue != $row["Game"]) { $controlBreakValue = $row["Game"]; array_push( $arrData["categories"][0]["category"], array("label" => $controlBreakValue)); $controlBreakValue == ""; } } } $arrData["dataset"] = array(); $i = 0; if ($resultData) { $controlBreakValue = ""; while ($row = mysqli_fetch_array($resultData)) { if ($controlBreakValue != $row["Team"]) { $controlBreakValue = $row["Team"]; array_push($arrData["dataset"], array("seriesname" => $controlBreakValue, "data" => array(array("value" => $row["Total"])))); $controlBreakValue == ""; $i++; } array_push($arrData["dataset"][$i-1]["data"], array("value" => $row["Total"])); } } } $jsonEncodedData = json_encode($arrData); $dbhandle->close(); echo $jsonEncodedData; ?> <html> <body> <?php $columnChart = new FusionCharts("msline", "myFirstChart" , 850, 300, "chart-1", "json", $jsonEncodedData); $columnChart->render(); ?> <div id="chart-1"><!-- Fusion Charts will render here--></div> </body> </html> ​ Chart output is attached. You can see the first value is duplicated.
