php - How to do order by case when on sphinx? -


how can set column priority sphinx search? in custom mysql code, following codes. how can re-code sphinx search?

$orderby = "order                          case when substring_index(n.eser_adi, '/', 1) '% $termsasil %' 1                            when substring_index(n.eser_adi, '/', 1) '$terms' 2                            when n.konu_basliklari '% $termsasil %'  3                            when n.konu_basliklari '$terms'  4                            when yazar_adi '% $termsasil %'  5                            when yazar_adi '$terms'  6                                when n.isbn '% $termsasil %'  7                            when n.isbn '$terms'  8                            when yer_numarasi '$termsasil%' 9                            else 10                         end asc";

well technically can put expression in select section

sphinxql> select id,if(col=2,1,2) mysort index order mysort asc

note, there isnt case statement, use if() same effect.

but there no or indeed substring_index function, wouldn't translate over.

however there search terms, manipulate query effect calculated weight. can use field-weights adjust relative weights. 

sphinxql> select id index   match('$terms (@eser_adi ^terms | @eser_adi ^terms | @eser_adi "^terms$" | @konu_basliklari $termsasil)')

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
