// or
$sparkline->setFillColorRGB(139, 28, 43);
// or for specific series
$sparkline->deactivateFillColor();
// or for all series
$sparkline->deactivateAllFillColor();

$sparkline->setData(array(.....)); // Set data set
$sparkline->getData(); // Get seted data
$sparkline->generate(); // If you want regenerate picture 

// Change base of height value (default max($data))
$sparkline->setBase(20);

// Change origin of chart value (yAxis) (default: 0)
$sparkline->setOriginValue(40);

// Add dot on first/last/minimal/maximal value
// Data set before used method
$sparkline->addPoint('minimum', 3, '#efefef');
$sparkline->addPoint('maximum', 3, '#efefef');
$sparkline->addPoint('first', 3, '#efefef');
$sparkline->addPoint('last', 3, '#efefef');

Multiple sparkline series

<?php

$sparkline = new Davaxi\Sparkline();

// For add series
$sparkline->addSeries([0,1,2,3]);
$sparkline->addSeries([2,3,5,6]);

// Or 

$sparkline->setData(
    [0,1,2,3],
    [2,3,5,6]
);

// For add point on series
$sparkline->addPoint('first', 3, '#efefef', 0); // Add point on series 0
$sparkline->addPoint('last', 3, '#efefef', 1); // Add point on series 1

// For fill colors, specify on last argument series index's
$sparkline->setFillColorHex('#8b1c2b', 0);
$sparkline->setFillColorHex('#8bdddf', 1);
// or
$sparkline->setFillColorRGB(139, 28, 43, 0);
$sparkline->setFillColorRGB(139, 28, 55, 1);

// For line colors, specify on last argument series index's
$sparkline->setLineColorHex('#1c628b', 0);
$sparkline->setLineColorHex('#1c62df', 1);
// or
$sparkline->setLineColorRGB(28, 98, 139, 0);
$sparkline->setLineColorRGB(28, 98, 55, 1);
